This book examines the issues relevant to the design of vector and pipelined computer systems using the Cray X-MP/24. The purpose of the book is to help the readers arrive at a deep understanding of how vector processing systems really work. These insights will be useful to the scientist who would like to obtain maximum performance from a vector machine, to the computer science student, and to the compiler writer. The book can also be used to supplement a regular textbook in a graduate or senior level course in computer architecture. The book looks at the overall design of the Cray X-MP and then explores the operation of the machine by looking at detailed timings of various instructions and code segments. It examines such issues as instruction issues and buffering, handling of jump instructions, use of registers to hold intermediate results, memory conflicts resulting from vectorization, optimal vectorization of multiple statement loops, and synchronization problems with multi-tasking. Detailed Gantt charts are provided to guide the reader through the timing issues.

This book is the second from this series of biennial symposia. The volume is intended as a forum for specialists working in various domains associated with Intensive Computing (Parallelism, Vectorization and Scalar), to discuss the state of the art. During the last decade, there has been sustained growth of scientific computing devices: expanding size of memories, incredible CPU performance unheard of just a few years ago, graphic tools transforming results treatment, networks drastically reducing communication time between computers, etc. It seems of prime necessity for the hardware designer to take into consideration the multiple and often conflicting needs of the scientific computing community, and for users to steadily devote time to update their knowledge of computing environments. Therefore, the main purpose of this volume is to give scientists an opportunity to investigate interactively areas such as Architecture of Supercomputers, Compilers, Algorithms, Computational Methods, Numerical Applications, and others.
